Nieve out at least six weeks

The news is in after Fernando Nieve left Sunday’s game with a leg injury, and the news isn’t good. He has been diagnosed with a muscle tear in his right thigh, making him the fourth Mets pitcher on the disabled list.

Nieve, who had pitched well for the Mets with a 2-2 record and a 2.95 ERA, will be out for at least six weeks. The Mets called up outfielder Cory Sullivan to fill Nieve’s roster spot until a new pitcher, likely Jonathon Niese, is called up to start Saturday.

Sullivan has been playing well with Triple-A Buffalo, batting .290 with 37 runs scored, 16 doubles, two home runs and 24 RBI in 85 games. The Mets management said they chose Sullivan over Nick Evans because he provides more versatility as an outfielder.
